ある。[Detailed Description of the Invention] (Industrial Application Field) The present invention prevents fusion between ceramic products and plywood when firing various ceramic products such as alumina substrates and ceramic powder molded products. The present invention relates to improvements in sheets for firing ceramic products used for firing ceramic products.

セラミックス製品どうしが融着する等の間匪があった。(Conventional technology) To prevent fusion when firing ceramic products,
A powder-containing sheet in which alumina or zirconia powder is dispersed inside a paper or plastic sheet, as shown in Japanese Patent Publication No. 60-8991, has traditionally been used, but the entire sheet shrinks significantly during firing. As a result, there was a gap where the ceramic products were fused together at the periphery.

波打ち、平滑性が損なわれることがあった。Therefore, the present inventors invented a sheet for firing ceramic products in which a coating layer consisting of ceramic powder such as alumina or zirconia and carbon powder was formed on the surface of the sheet, and the inventors proposed the sheet in Japanese Patent Application No. 182727-1983. That's what I did. However, since ceramic powder, carbon powder, and their binders have different specific gravity, it is difficult to prepare a uniform slurry, and the coating layer formed on the sheet becomes uneven, resulting in partial defects on the sheet during firing. Shrinkage or cracks may occur, causing the sheet to be wavy and its smoothness to be impaired.

摩耗するという問題もあった。In addition, since each batch of slurry in sheets for firing ceramic products is a homogeneous sheet containing the same ceramic powder, it is difficult to produce a wide variety of products in small quantities, and it is difficult to cut large sheets into desired sizes. There was also the problem that the cutter was significantly worn due to the ceramic powder contained in the coating layer.

効果を発揮することができる。In particular, in the present invention, carbon powder layers (2), (2) are formed on both surfaces of the combustible sheet (1), so carbonization of the combustible sheet (1) is promoted during firing, and the entire sheet is The shrinkage rate is suppressed to the same degree as the firing shrinkage rate of an alumina green sheet, and there is no possibility of fusion of the ceramic products to each other even at the periphery. Further, in the present invention, a carbon powder layer (2) is provided on the surface of the combustible sheet (1).
), (2) and the high melting point powder layer (3) are formed separately, so that each component in the slurry can be coated with a mixture of carbon powder and ceramic powder. Non-uniformity of the coating layer due to non-uniformity of specific gravity does not occur. Therefore, the entire sheet of the present invention is extremely homogeneous, and when a green sheet is fired using the sheet of the present invention, the fired ceramic substrate also has excellent smoothness without waviness or pinholes. Become. The sheet of the present invention can also be used in the same way when firing ceramic powder molded products, and can exhibit excellent adhesion prevention effects.
